Summary
Aural foreign bodies are common, with this study analyzing 509 cases over 16 years. Organic foreign bodies were more prevalent in summer months, particularly in children under 9 years old.
Area of Science:
- Otolaryngology
- Emergency Medicine
- Public Health
Context:
- Aural foreign bodies are frequently encountered in clinical practice.
- Systematic analysis of large case populations is limited.
- This study retrospectively reviewed 509 cases of aural foreign bodies.
Purpose:
- To systematically analyze a large cohort of aural foreign body cases.
- To identify demographic, seasonal, and etiological patterns.
- To understand the incidence and characteristics of aural foreign bodies.
Summary:
- A total of 509 cases were analyzed from January 1986 to December 2001, representing 0.74% of new visitors.
- The majority of cases (68.4%) were seen in emergency settings.
- Key demographics include a higher incidence in males (60.3%), peak age group under 9 years (35.8%), and a bimodal seasonal peak in July and August.
- Inorganic foreign bodies (56.6%) were more common than organic (40.5%), with organic types showing a correlation with warmer months.
Impact:
- Provides comprehensive data on aural foreign bodies, aiding clinical management.
- Highlights the importance of considering seasonal factors and age groups in diagnosis and prevention.
- Contributes to the understanding of epidemiological trends in otolaryngology.
